Abstract

Have been done by a research identify the structure of rock basement as long as roadway province at potency area landslide the District of Sumberjaya West Lampung, using method of resistivity of configuration Wenner-Schlumberger. The conducted to data processing use the program Res2Dinv and yield the model of rock layer which have potency to slide. Be base on to model analysis can be interpretation that geology structure of under surface at research area highly varied, consisted of the young rock volcanic sediment which mixed with the alluvium occupy the topmost position representing top soil. Hereinafter there are claystone-tuff layer, certain period the interlude by sandstone-tuff is located until deepness 20 meter. Last of more compact at the resistivity more than 250 ohm.m interpreted as basement in the form of rock andesitic at deepness more than 20 meter. Interpreted to this top soil experience of landslide in infiltration of the rains arrive which is resulted from a high level steepness store and incidence of instability effect of the infiltration rainwater. Besides existence of sandstone-tuff of below top soil layer cause the degradation to rock rigidity of effect of side by water which is because of height of the rock porosity.
